Joechapl Posted January 19, 2017 Report Share Posted January 19, 2017 Evening all, I changed the engine in my Lupo as the bottom end was finished. The old engine didn't have an EGR port on the cylinder head but my new engine does. I changed all the wiring but the car misfires and sounds unusual. Is there any way to fix it? I also read a thread on here about the EGR valve making the car misfire. Should i blank it and put the old wiring back on? Many Thanks!
